Projectile launching toys include a surface suitably configured to support and guide a projectile, a lever pivotally mounted so as to traverse a portion of the surface in the direction the projectile is being guided, a manual actuator coupled to the lever to manually move the lever from an initial position to a second, pivoted position to launch the projectile and a return member coupled with the lever to automatically return the lever to its original position after being manually moved and released. |
